Application filed retmar e7, iii-25. Serial in. 12,115).

To all whom it may concern:

Be itknown that I, WALLACE R. GILLAM, a citizen of the United States, residing at Tallmadge, in the county of Summit and State 01" Ohio, have invented a new and Improved Means for Adapting iVide-Bnse Cushion Tires to Narrow-Base Rims, of which the following is a, specification.

My invention has for its object to provide 11163115 by which preferebly wide base cushion tires may he mounted on standard narrow base rims without the necessity of removing the standard rim from the wheel; more particularly the invention has for its object to provide means whereby a cushion tire that 1s molded permanently on a, rim can he used in replacement of pneumatic tires on standard rims of the well known Budd-Michelin type, Where the standard rim is e fixture with the W-i'lBBl or is a, part of the wheel itself, thus enabling cushion tire equipment to replace pneumatic tire equipment at a low cost and with n mini mum expenditure of time and labor.

My invention has been especially ciesigned with a view of replacing pneumatic tire equipment in taxi cab service, with cushion tires of wide base onol greater on ing capacity.

ore suhordinetely, the invention resides in these novel features of construction, oombinetion anti arrangement or" parts oil of which will he first fully described, then he pointed out in the epmnoleo chime end; iilustreteo in the accompanying drawing, in whie Figure 1 is a side elevation illustrating the epplicetion of my invention. i

Fi re 2 is e cleteil sectional nerspeotive it nueeniciiuin disk wheel we rim with my invention npplieii, the cushion tire heing omitted,

Figure 3 is a crow section on the line 33 m? Figure 1.,

Figure t is e detail section on e mail reels showing the standard i8u&&-h lichelin rim and wheel as at present us d with pneumetic tires.

in the crowing I have shown in Figure 4 a cross section tor the urnose oi diefining the structure which I ave referred to es the Bnddhiichelin type anti whiieh it is the urpoee of my resent invention. to orient ror use with ens on tires the drawing 1 dmignntes e etnnfinrn type of steel olisk wheel (Budd) on the periphery of which a, standard rim 3 for demountable pneumatic tires is located under the presentproctioe, the rim 3 being usually permanently secured by rivets or welding to the periphery of the Wheel.

The standard rim (Michelin), ns shown in Figure 4, consists of a loose 3 secured to the periphery 2 of the wheel 1 and having a. flange 4 at one side to engage one side of the pneumatic tire P, and having e (lepression or groove 5 at the other side, hook shape in cross section, to receive the looking ring 7 that holds the removable sicle ring 6 in P13208- In adapting the stanclm'ni Budd-Michelin Wheel to use with cushion tires 1 fiiscarti the rings 6 and 7 entirely and provide the cushion tire C with espwiel rim her ing a, hose 9 and en upwardly and outwardly niclined side portion 10 to lie on the out- WMClly curved edge of the flange t oi the stenolercl rim 3. The special rim 9 also has a, depression '11 which is eclnpteol to, lie normolly almost in contact with the hose 3.

In oroer to hold the rim 9 in pines tightly, I provide lugs 13 having o wedge portion 14 to ricle on the ed; 8 of the content wrtion 5 of the stan arcl rim 3, the lugs 8 heing ndaptwl' to he drown over anti secured to the wheel 1 to bolt and nut devices 15 held in holes ori led. therefor in the wheel 1.

Slocum-the ln s 13 not he cirnwn up tight enough or she e they worlr lows slightly the rim of the cushion tire will rifle on its projections ill at one side enfl on the surface 10 ot the other, end take the weight 08 the lugs 15.

From the foregoing it will he seen that I have provided a simple enfi efi'ective means for adopting" the standard Butte?- Michelin wheels to use cushion tires, without the necemit of proviing the wheels with new telly I ends or rim portions-lino without the necessity of the epplicntion of ex ensive lehor.

rem the fore oing oeeeription, tehm in connection with t ie'necompnnying drawing it is thought the complete construction on advantages of my invention will he reeclily went to those skilled in the ert.

.et 1 claim is:

L A means for adopting cushion tires to standard rims of the quick cietnchehle type,

which rims comprise a base with one side flange and a locking ring groove at the opposite side; said means comprising a special rim which is adapted permanently to carry :1 cushion tire, said special rim comprising a base and two side flanges-one of which is adapted to rest on the side flange of the standard base, securing wedge lugs fastened to said specialrim and ada; ted to lie between the base of the special rim and over the locking-groove-edge of the standard rim, said wedge lugs each having a portion projecting radially, and fastening bolt and nut devices to hold said lugs in place, thereby to secure said rims together.

2. In combination, a standard rim comprising an annular base having an outwardly projected flange at one side and an inwardly projected groove at the other side, and a special rim of wider dimension and. greater diameter than the standard rim, said special rim comprising an annular base'having outwardly projected flanges, one of which includes an inclined contacting part to engage the outwardly projected flange of emons the standard rim, wedge lugs inserted between said rims at the side adjacent the inwardly pro'ected groove and means to secure said lugs n place and tighten said rims together.

3. In combination, a disk wheel carrying a standard rim com risin an annular base having an outward y pro ected flange at one side and an inwardly projected groove at the other side, and a special rim of Wider dimension and greater diameter than the standard rim, said special rimcomprising an annular base having outwardly projected flanges, one oi. which includes an inclined contacting part to engage the outwardly projecting flange of the standard rim, wedge lugs inserted between said rims at the side adjacent the inwardly projected groove, means to secure said legs in place and tighten said rims together, said lugs being permanently secured to said special rim and detachably secnrable by said securing means to said wheel.
